Odd. My post contents vanished.
In brief - having a tidy up of my reference book collection, moving on the duplicate titles and books superfluous to my buying interests... so just seeing if anyone here might be interested.
I'm still working my way through the titles, and these ones are mostly on ancient glass through to Victorian. Titles on modern/contemporary glass to follow. The non-English titles are profusely illustrated, and so are still useful to those who can't read German, Danish or French.
I'm just looking to get back what I paid, plus P&P at cost. If anyone is interested, or wants more info/photographs, drop me a message.
